Configure the LAG Interfaces as Dynamic
After creating a LAG, to configure the dynamic LAG interfaces, use the
command.

Set the LACP Long Timeout
PDUs are exchanged between port channel (LAG) interfaces to maintain LACP sessions. PDUs are
transmitted at either a slow or fast transmission rate, depending on the LACP timeout value. The timeout
value is the amount of time that a LAG interface waits for a PDU from the remote system before bringing
the LACP session down. The default timeout value is 1 second but you can configure it to be 30 seconds.
Invoking the longer timeout might prevent the LAG from flapping if the remote system is up but
temporarily unable to transmit PDUs due to a system interruption.
Note:
The 30-second timeout is available for dynamic LAG interfaces only. You can use the
long-timeout
